Rohde & Schwarz enhances test and measurement to help Telesat evaluate satellite networking link designs
MUNICH – Rohde & Schwarz in Munich is introducing enhanced measurement options across the company's testing equipment for next-generation satellite networking.
Telesat Corp. in Ottawa, for example, is using Rohde & Schwarz’s advanced testing equipment to optimize service link designs of the Telesat Lightspeed low-Earth-orbit (LEO) satellite network.
Telesat Lightspeed provides ubiquitous, affordable, high-capacity links at fiber-like speeds, with global service anticipated by the end of 2027.
Telesat uses the Rohde & Schwarz signal generator R&S SMW and spectrum and signal analyzer R&S FSW to qualify and verify new RF chipsets and satellite modems across several different vendors.
Verifying modem performance
The test and measurement instruments test receiver chipsets, as well as evaluate and verify modem performance for several different waveforms -- notably DVB-S2X and DVB-RCS2 -- which has helped Telesat develop beam hopping and superframe to help DVB-RCS2 return channels that are larger than what has previously been available in satellite network deployments.
The Rohde & Schwarz test capabilities have helped Telesat evaluate modem and chipset manufacturers, and validate system performance “The integration of Rohde & Schwarz test equipment into our LEO development labs allows Telesat to build automated development and test environments to support 24/7 availability for onsite and remote testing, says Aneesh Dalvi, Telesat’s vice president of Lightspeed systems development.
